SPIKE AND DRIFT-BOLT PULLER.

SPECIFICATION forming part of Letters Patent No. 576,462, dated February2, 1897. Application filed May 20, 1896. Serial No.592,355. (No model.)

To all whom, it may concern.-

Be it known that we, LAWRENCE O. LOUNS- BERRY and ALEXANDER CAMPBELL,citizens of the United States, residing at Albion, county of Levy, Stateof Florida, have invented a new and useful Spike and Drift-Bolt Puller,of which the following is a specification.

Our invention relates to improvements in spike and drift-bolt pullers;and the objects of our improvements are, first, to provide an instrumentthat can be quickly applied to the spike or bolt of any size; second, toprovide an instrument that takes an immovable hold of the article to bepulled. We attain these objects by the mechanism illustrated in theaccompanying drawings, in which- Figure l is a representation of themovable jaws. Fig. 2 is a side view of the puller, showing how the jawsare operated by the lever. Fig. 3 is a front view. of the foot of thepuller, showing the jaws in position in the slots.

It will be noticed that the movable jaws B are narrower in their frontwidth n than in the back width 0. The slots y in the foot G and the faceof the foot- G along which these jaws move are made to correspond withthe shape of the jaws, the object being to force the jaws inwardly asthey are pushed out from the rear of the foot. The clutching-faces E ofthe jaws are made to slope back from thebottom, so that when the jawsare forced together the bottom edge will have a chance to work under thehead of the spike or bolt. The circular projections O are threaded andfitted with two nuts m. Fig. 2 shows how the part 0 extends through thefoot G, coming out at the back of the foot and passing through the partP of the lever L. The nuts m are to adjust the jaws to the lever, andwith them the jaws can be fitted to different-sized spikes as desired.The lever L is adjusted to the foot G by the lever is pressed down thejaws B, being attached to it by means of the nuts m, will be pressedforward and inwardly, thus firmly clutching the spike or bolt.

D is a heel-piece attached to the bottom of the foot-piece G and acts asa brace for G, preventing the foot-piece from slipping away from thespike or bolt as it is being drawn.

The holes in the arm P are made sufliciently large to allow of somemovement of the bolts 0 therein as the lever is oscillated. The holesalso in the foot-piece G, through which the bolts 0 project,are madelikewise large enough to allow of some movement of the bolts 0 therein.In drawing a spike or bolt, after the arm P comes in contact with theback of the foot G further converging movement of the jaws is prevented,and in the actual drawing of the spike the lever and footact as anintegral structure. After a bolt has been partially drawn the jaws canbe released by a reverse movement of the lever and a new hold securedany distance below the head by the jaws biting into the side of thebolt, owing to the converging movement of the jaws.

hat we claim as our invention is-- The combination in a spike anddrift-bolt puller of the foot-piece G, made with the heelpiece D, fittedwith converging jaws B which move in slots y, the converging jaws beingconnected to and operated by a lever L which is pivotally connected tothe foot-piece G.
